WASHING-MACHINE CYLINDER.

Specification of Letters Patent.

Patented Feb. 19,:i9di8.

Application filed October 4, 1915. Serial No. 54,062.

To all whom it may concern:

Be it known that l, Gnoacn lVILLIAM A1.- DRICII, a citizen of the United States, residing at Antigo, in the county of Langlade and the State of Wisconsin, have invented a new and useful Washing-Machine Cylinder to be Used for Dry-Cleaning, Washing, and Carpet-Cleaning Machines. of which the follow ing is a specification. I

My present invention relates to new and useful improvements in washing machines more particularly of the type embodied in my co-pending application for patent filed Oct. 4, 1915, Serial No. 54,063.

It is in general the object of my present invention to embody the general advantages of the structure of my aforementioned application in a wooden cylinder.

Amore specific object resides in the provision of an arrangement wherein the various stave and rib portions of the cylinder may be readily replaced upon becoming worn, to thus procure an indefinite length of life of the cylinder, and it is a further object in this connection to provide an arrangement wherein the rib members of the cylinder may be reversed upon becoming worn.

A still further object of the invention resides in the provision of novel means for introducing cleansing fluid into the cylinder, whereby said cleansing fluid serves as a 111- bricating medium for the clothes in their rubbing engagement with the ribs.

With the above and other objects and advantages in view the invention resides more particularly in the novel combination formation and arrangement of parts hereinafter described and pointed out in the accompanying claim.

In the drawings:

Figure 1 is a perspective view of a wooden stave cylinder constructed in accordance with my present invention.

Figs. 2, 3 and 4 are partly diagrammatic transverse sectional views through the cylinder showing the successive lifting, dropping, and rubbing actuation of a mass of clothes therein.

Fig. 5 is an end view of the cylinder.

Fig. 6 is an elevational view of one of the end rubbing plates of the cylinder.

Fig. 7 is a transverse sectional view therethrough on the line 7-7 of Fig. 6.

Fig. 8 is an elevational view of one of the end head plates of the cylinder.

Fig. 9 is a detail view of one of the latch members of the door.

Referring now more particularly to the accompanying drawings, the peripheral portion of the cylinder comprises a series of wooden staves 20, certain of the staves being spaced apart for the disposition therebetween of a series of rubbing rib boards 21 and a single relatively large lifting rib board 22, the spaces between the rubbing ribs being considerably less than the spaces between the lifting rib and adjacent rubbing rib whereby to procure squeezing pockets as in my said co-pending application. The washing operation procured by the present cylinder being similar to the operation procured in my said application with the exception that the ribs are not slanted and hence do not procure a positive longitudinal movement of the mass of clothes in the cylinder. The staves and rib boards are bolted or otherwise secured at their ends to the peripheral portions of end head plates 23, with the exception of a certain number of staves at one side'of the lifting rib board 22 which are secured to door straps 24 hinged to the connected body of staves to form a door, the outer portion of this door comprising a relatively wide and heavy stave 25 in which is set at its ends a pair of spring urged locking plungers 26 adapted to engage in socket members 27 carried by retaining bands 28 disposed about and secured to the ends of the main body of staves and rib boards.

The end portions of the rubbing rib boards 21 and lifting rib board 22 engage in cut away peripheral portions 29 and 30 respectively of the end head plates and said rib board end portions are also disposed in similar cut away portions 30 and 31 respectively of a pair of end rubbing plates 32 which are fitted in the ends of the cylinder against the head plates 23, these end rubbing plates being provided with series of inwardly struck radial rubbing ribs 33. Bolted to the head plates 23 are pintle hubs 34 whereby the entire cylinder may be journally mounted.

To set up an agitation of cleansing flu1 d in an outer drum in which the cylinder 1s adapted to be disposed the staves 20 are provided with longitudinal relatively wide grooves35 in their outer faces, the walls of said grooves being oppositely and inwardly inclined and for scooping cleansing fluid into the cylinder to lubricate the clothes upon their engagement with the rubbing ribs, oppositely inclined longitudinal serles of passages 36 communicating with the 1011- gitudinal grooves are formed in the staves whereby cleansing fluid is scooped Into the cylinder upon rotation of the cylinder in either direction.

By the foregoing that a cylinder has been provided which Is of maximum simplicity and which may be readily assembled and disassembled to permit'the substitution of fresh staves or rib boards upon wear. Also it is: noted that both edge portions of each rib board are reversed upon wear occurring at the exposed ed e portions thereof.

What is claimed is:

' A cleaning cylinder comprising a peripheral wall formed of staves having a series of o positely inclined erforations extending t erethrough, spaced rubbing ribs and a lifting rib, close fitting joints being provided between the peripheral edges of said staves, rubbing ribs and lifting rib and said staves having their inner faces smooth and unbroken and being provided in their outer surfaces with central longitudinally extending grooves, the walls of said grooves being oppositely andv inwardly inclined, said inv clined perforations communicating with descrlption 1t 1s seen the said central longitudinally extending grooves, and end wall members closing the ends of the cylinder.
